Embodiment 1

[0010] A PVC formula with high oxidation resistance of the present invention is made of the following raw materials in parts by weight: 70 parts of PVC resin, 4 parts of calcium stearate, 3 parts of zinc oxide, 6 parts of hexamethylphosphoric triamide, anti-impact agent 1 part, 2 parts of chlorinated paraffin, 0.5 parts of additives.

[0011] The auxiliary agent is composed of one or more than two kinds of plasticizer, wetting agent and stabilizer.

Embodiment 2

[0013] A PVC formula with high oxidation resistance of the present invention is made of the following raw materials in parts by weight: 90 parts of PVC resin, 6 parts of calcium stearate, 6 parts of zinc oxide, 8 parts of hexamethylphosphoric triamide, anti-impact agent 2 parts, 3 parts of chlorinated paraffin, 1.3 parts of additives.

[0014] The auxiliary agent is composed of one or more than two kinds of plasticizer, wetting agent and stabilizer.

Embodiment 3

[0015] Embodiment 3 is the optimal embodiment of the present invention:

[0016] A PVC formula with high oxidation resistance of the present invention is made of the following raw materials in parts by weight: 80 parts of PVC resin, 4.1 parts of calcium stearate, 5 parts of zinc oxide, 6 parts of hexamethylphosphoric triamide, anti-impact agent 1.4 parts, 2.6 parts of chlorinated paraffin, 0.9 parts of additives.

[0017] The auxiliary agent is composed of one or more than two kinds of plasticizer, wetting agent and stabilizer.

[0018] To sum up, the PVC pipe produced by using this formula can enhance the impact resistance and strength, and the added hexamethylphosphoric acid triamide can not only greatly improve the oxidation resistance of PVC pipe, but also has a relatively low cost, which is suitable for popularization and application .

Abstract

The invention discloses a good-oxidation-resistance PVC formula, which is characterized by comprising the following raw materials, by weight part, 60-100 parts of a PVC resin, 4-7 parts of calcium stearate, 2-7 parts of zinc oxide, 6-8 parts of hexamethylphosphoramide, 1-2 parts of an impact-resistant agent, 2-3 parts of chlorinated paraffin, and 0.5-1.3 parts of an auxiliary agent. The formula has the beneficial effect that a PVC pipe produced from the formula has improved impact resistance and strength, and hexamethylphosphoramide is added to greatly improve oxidation resistance of the PVC pipe and reduce the cost of the PVC pipe. The formula is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a PVC formula with high oxidation resistance. Background technique [0002] The main component of PVC pipe is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. PVC is deeply loved in the world today, and it is quite a popular and widely used synthetic material. PVC pipe is a mature pipe, mainly used in water supply and drainage projects. PVC pipe has the advantages of acid resistance, alkali resistance, corrosion resistance and high strength, but its impact resistance is relatively poor. Contents of the invention [0003] The invention provides a PVC formula with high oxidation resistance, and the PVC pipe produced by using the formula can enhance the impact resistance and strength. [0004] In order to achieve the above object, a PVC formula with high oxidation resistance of the present invention is charact...
